I'm also thinking of this, since I will not cry too hard if/when it gets ripped clean off the car while working on ARA stage rallies (unlike any of the real splitters, which  would make me wail like a baby when they get destroyed).

I do wish that someone made these stick-on type 'splitters' more in a flexible 'shallow air dam' 
vertical style, like the WRC cars use on the bottom of their bumper edges.
